A method for enhancing the antiseptic performance of bamboo products

Abstract

The invention discloses a method for enhancing the anticorrosion performance of a bamboo product. The method comprises the following steps: mixing polyvinyl alcohol, epichlorohydrin and sodium hydroxide, adjusting the temperature, performing stirring, adding the obtained mixture into ether to achieve precipitation, filtering the obtained solution, adding talcum powder and an ethanol solution, andsequentially performing uniform mixing, ultrasonic dispersion, stirring and microwave irradiation to obtain a first preformed material; adding a preservative, a wetting agent, a dispersant, an antifreeze agent, a thickener and a leveling agent to water, performing stirring, adding disproportionated rosin and the first preformed material, performing uniform stirring, sequentially adding a styrene-acrylic emulsion, a silicone emulsion, a film-forming additive and an antifoaming agent, and performing uniform stirring to obtain a second preformed material; preprocessing and drying 5-to-8-year-oldbamboo, placing the bamboo in water in a closed container, and sequentially performing heating, high-pressure standing, cooling, filtering and natural drying to obtain a third preformed material; andimpregnating the third preformed material in a phenolic resin glue, performing hot press molding, coating the surface of the hot-pressed bamboo with the second preformed material, curing and drying the coated bamboo to obtain anticorrosive bamboo skins, and weaving the anticorrosive bamboo skins to obtain the bamboo product.

Description

technical field [0001] The invention relates to the technical field of bamboo products, in particular to a method for enhancing the antiseptic performance of bamboo products. Background technique [0002] The chemical anti-corrosion method of bamboo generally uses preservatives to hinder the basic metabolism of fungi, so as to achieve the purpose of inhibiting the growth and reproduction of fungi and even killing decaying bacteria. Its advantages are good anti-corrosion effect and long residual time. The distribution is also uneven, and rarely reaches the inner layer. [0003] As a transparent coating, varnish is applied on the surface of an object and forms a smooth film after drying, showing the original texture of the object surface. The bamboo surface texture can be maintained, and the anti-corrosion effect is also remarkable, but there are technical problems of poor anti-corrosion and anti-bacterial performance in the process of coating the bamboo surface, which needs ...
